    TOPOI/PARP-1-IN-1

    		PARP Topoisomerase Apoptosis Cancer
    TOPOI/PARP-1-IN-1 (Compound B6) is an orally active, low cytotoxic TOPOI/PARP dual inhibitor with an IC50 value of 0.09 μM for PARP1. TOPOI/PARP-1-IN-1 can effectively inhibit the proliferation and migration of cancer cells. TOPOI/PARP-1-IN-1 also causes cell cycle arrest in the G0/G1 phase and induces apoptosis. The tumor growth inhibition rate (TGI) of TOPOI/PARP-1-IN-1 in mice is 75.4% .

    TOPOI/PARP-1-IN-2

    		PARP Topoisomerase Apoptosis Cancer
    TOPOI/PARP-1-IN-2 (compound 6c) is a dual PARP-1 and topoisomerase 1 (TOPO-1) inhibitor with IC50s of 32.2 nM and 46.2 nM, respectively. TOPOI/PARP-1-IN-2 shows a selectivity for PARP-1 over PARP-2. TOPOI/PARP-1-IN-2 disrupts the cell cycle at the S phase and induces apoptosis in NCI-60 cancer cell lines .

    iNOS/TopoI-IN-1

    		NO Synthase Topoisomerase Apoptosis NF-κB Inflammation/Immunology Cancer
    iNOS/TopoI-IN-1 (compound AuL9) is a multi-target hybrid molecule with anti-tumor, anti-inflammatory and antioxidant activities. iNOS/TopoI-IN-1 inhibits the growth of breast cancer cells MCF-7 and MDA MB-231 in vitro with IC50 of 3.5 μM and 6.3 μM, respectively, and induces DNA damage and apoptosis of breast cancer cells by inhibiting human topoisomerase I (TopoI) (Ki=2.72 μM). In addition, NOS/TopoI-IN-1 inhibits the expression of iNOS by inhibiting the activation of NF-kB (Ki=1.49 μM) .

    GI-149893

    		Topoisomerase Cancer
    GI-149893 is a selective topoisomerase I (TopoI) inhibitor. GI-149893 prevents DNA religation and induces irreversible DNA damage in tumor cells. GI-149893 is promising for research of cancers (e.g., colon carcinoma HT-29/SW-48, breast MX-1, prostate PC-3 xenografts) .
